InnoDB status will be basically useless, as full-text is only applicable
to MyISAM, and indeed your status output shows only one transaction is
running (the one running 'show innodb status') and InnoDB has done zero
work since the server was started (look in the ROW OPERATIONS section).
So your server isn't using InnoDB for any tables (at least none you've
queried since starting the server).
But you're still allocating some memory and other resources to it. If I
were you I'd put the following in your /etc/my.cnf just to ensure InnoDB
isn't interfering or complicating anything:
